The weights of black bears are normally distributed with a mean of 264 kg and a standard deviation of 38 kg. Let X be the weight of a randomly selected black bear. Use this information for exercises 2 and 3.
2. If P(a < X < 264) = 0.1139, find the value of a. (You must show work and/or TI
calculator commands to receive credit. Round your answer to the nearest kg.)
3. If P(264 < X < b) = 0.2362, find the value of b. (You must show work and/or TI
calculator commands to receive credit. Round your answer to the nearest kg.)
